Brass. The Hebrew word, nechosheth is improperly translated by "brass." In most places of the Old Testament, the correct translation would be copper, although it may, sometimes, possibly mean bronze, a compound of copper and tin. Indeed, a simple metal was obviously intended, as we see from Deuteronomy 8:9; Deuteronomy 33:25; Job 28. Copper was known at a very early period. Genesis 4:22.
